hidden form fields

[Aymen++]

what is the use of using the hidden form fields?

[liorean]

Things you might want to send to a serverside script but aren't related to user input, javascript output to a serverside script, to carry on a value from a previous form in a sequence of form pages, etc.

Basically its one of those things that you might not use very often but you are sure glad its there when you need it. They can come in very handy.
